had to the accompanying drawings, in

which Figure 1 is an end elevation partly in section, showing the application of my invention to a journal box; Fig. 2 is a plan thereof partly in section; Fig. 3 illustrates a modified form of my invention showing an end elevation partly in section; and Fig. 4 is a plan thereof partly in section.

My invention relates to the manufacture of journal boxes and particularly to casting inserts or wearing plates in the pedestal guides of journal boxes. I have found it desirable, especially where boxes made of malleable iron are employed, to apply the wear plates in the pedestal guides of the boxes after the malleableizing process has been completed. To this end, I apply molds about the pedestal guides of the boxes and cast wearing plates or inserts therein, after the box has been otherwise finished. My invention also consists in the features which I shall hereinafter describe and claim.

Referring to the drawings, 2 indicates the journal box pedestal guide flanges, and 3 a mold section which has a projection 4 extending between the flanges, leaving a space or cavity 5 conforming to the shape of an insert which is to be poured therein. The mold 3 also has portions 6 which ,overlap the top and bottom of the box respectively and comprise a closure over the upper and lower ends of the guides. Upon the top of the mold is also a mold section 7 provided with a pouring cup 8 opening into gates 9, communicating with the cavities 5, by which the mold is poured.

The molds 3 are secured upon the journal box by means of a yoke shaped clamp 10 and a base plate 11. The molds 3 preferably have tapered outer faces 12 which are engaged by corresponding tapered faces 13 on the yoke by which the molds are wedged inwardly against abutments 14 on the yoke and shoulders 15 on the base plate. It will thus be seen that by the bearing of the mold sections against the abutments 14 and the shoulders 15, that these sections will always be held a definite distance apart.

To provide for the accurate location of the clamp and base plate, the inner faces of the abutments 1 1 on the clamp engage the ends of the ribs 16 on the top of the journal box, and the lugs 17 on the inner faces of the abutments 14 seat between the ribs 16, while the base plate is provided with dowels 18 which seat in sockets 19 in the bottom of the box.

To prevent misrunning of the metal during pouring due to variation in the boxes, the joint 20 between the face of the guide flanges and the mold maybe provided with a suitable packing as shown.

In Figs. 3 and 4, I have shown an embodiment of my invention applied to a box having only one pedestal guide on each side, and in which the mold sections are wedged directly against the box. The clamp is centered upon the box by means of the projections 21 which enter the recess 22 on the box and bear against the sides thereof, and the base plate 22 is alined with reference to the box by means of the lugs 23 which engage the outer corners of the pedestal guide flangesj The mold sections are properly alined by the lugs 23 on the base plate and by being pressed inwardly against the shoulders 24 on the top of the box.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described, but recognize that various modifications embodying the substance of the invention are possible within the scope of the invention claimed.

What I claim is:

1. In apparatus for casting wear plates in the pedestal guides of journal boxes, mold sections arranged on opposite sides of the journal box, a clamp holding said mold sections in spaced relation to one another, said clamp also seating upon the journal box to center said journal box between said mold sections; the mold sections and journal box providing cavities in which wear plates may be cast.

2. In apparatus for casting wear plates in the pedestal guides of journal boxes, mold sections arranged on opposite sides of the journal box and providing cavities e for the casting of Wear plates, a clamp and a base plate holding the mold sections in spaced relation to one another and center ing the journal box .between the mold sec- 5; tions.
